BUTTON.

SPECIFICATION forming part of Letters Patent No. 352,363, dated November 9, 1886.

Application filed November 23, 1885. Serial No. 183,768. (No model.)

which- Figure 1 is a central vertical section of the head of my button. Fig. 2 is a plan of the same. Fig. 3 is a central vertical section of a similar button with a covering-cap and the attaching device. Fig. 4 is a central vertical section of the stud in position before theparts are fastened together. Fig. 5 is a similar section with the parts fastened together. Fig. 6 is a similar section of a modification,whichwillbe hereinafter explained.

This invention relates to certain new and useful improvements in buttons of that class in which the front and back are made detachable, and are held together, when engaged, by thelateral pressure of spring-arms in or upon the stud; and it consists in the peculiar combinations and the novel construction and arrangement of parts, all as more fully hereinafter described and claimed.

Referring by letter to the drawings, A designates the head of the button, which may either be made as shown in Fig. 1, or be covered with a cap, B, as shown in Fig. 3. The head consists ofa tube formed with a base, a, which is corrugated, as shown, to form an annular ridge or projection, c, and its outer edge is preferably turned under, forming a recess, a, the purposes of both of which will hereinafter appear. If the cap is employed, it may be united to the part A by slightly turning its edge under the base, as shown in Fig. 3; or the base may be made without the turnedun' der part, and the edge of the cap be turned farther under, as shownin Fig. 6, so asto leave .a recess between the turned-under edge of the cap and the base, similar to that formed in the base in Figs. 1 and 3.

C is an eyelet of any approved construction, the upper end of which is slightly larger than the opening in the base, and is used for securing the button to the fabric by first placing the latter in position, and then forcing the eyelet 0 through from the other side, and as the upper end of the eyelet strikes against the ridge 0 of the base of the head it is deflected or turned outward into the recess a, formed in the base, or that between the base and the turned-under edge of the cap, as the case maybe, thus firmly uniting the parts and securing the head to the fabric.

The tube A is split longitudinally or vertically, preferably as shown in Figs. 1 and 2 that is, so. as to form four spring-arms; butI do notlimit myself to this precise form, as it is evident that the nu mber of slits may be varied, so as to make two, three, or more arms with, out departing from the spirit ofmyinvention, The object of splitting the tube is to allow the same to yield when the stud is inserted therein. Near the center ofits length this tube ispressed inward to form an annular rib or projection, d, designed to engage the notch in the stud when the latter is inserted in said tube.

The stud is formed of the tube D, having a round head, a flange, D, and a notch ,or annular groove, d, and the tube or plug E, having a flange, e. The shank of this tube or plug Eis put through the fabric and the tube D forced on over it, with the fabric held firmly between the flange D of the tube D and the flange e, as shown in Fig. 4. When in this position the two tubes are united by means of a suitable instrument, by which one or more indentations are formed in the tubes, as shown in Fig. 5, themet-al of the indentation of the outer tube entering the depression in the in ner tube, thus uniting the two tubes, as will be readily understood.

To fasten the two parts of the button-that is, the head and the studtogether, it is only necessary to force the stud into the aperture in the head,when the upper parts of the tube will spring open and allow the head of the stud to pass through till the notch in the stud is coincident with the ridge d in the tube B,when the spring-arms resume their normal position, and the ridge d engages the notch in the stud. The button is separated by pulling on the head or stud, or drawing both in opposite directions, when the two parts will be readily separated.

It is evident that if the plug is madeso large as to require force to push it into the stud it will be held securely without the indentations.

I have shown a ridge on the tube; but it is obvious that if the ends of the arms thereof are farther apart than they are near their middle portions the friction will hold the stud without said ridge.

What I claim as new is- 1. In a separable button, the combination, with ahead provided with a base having on one side a turned-under flange, forming a recess, and a split tube on the opposite side of said base, forming spring-arms, of a fastener, as 0, adapted to be expanded into the recess in the base when forced against the under side of the same, substantially as described.

2. In a separable button, the combination, with a head provided with a base having a turned-under flange, forming a recess, and spring-arms provided with ridges or projections between their ends and the base, of a fastener, as 0, adapted to be expanded into the recess in the base when forced against the under side of the same, substantially as described.

3. In a separable button, the combination, with a base having asplit tubeforming spring arms rising therefrom, said arms being provided with ridges or projections between their ends and the base, of a cap having its lower edge turned below said base, and a fastener, as 0, adapted to be forced outward toward the lower end of a cap by contact with the base, substantially as described.

4. The combination, in a separable button, of acylindrical hollow stud having a notched neck near its top of smaller diameter than the body of the same, and a base, with a cylindrical plug, E, fastened therein below said neck and having flange e, substantially as described.

5. The combination, in a separable button, of a hollow stud having a notched neck and a base with a cylindrical hollow plug, E, having flange e fastened in said hollow stud, and having the sides of both stud and plug indented, substantially as described.

6. The combination, in a separable button, ofa head, A, having a base and a split tube rising therefrom, and forming spring-arms with ridges or projections between their ends and the base, and a stud having a notched neck passing between and embraced by said arms, with a cap covering said arms and stud, substantially as described.

In testimony whereofI aifix my signature, in presence of two witnesses, this 21st day of November, 1885.
